### How To Size A Pump Blackmonk Engineering

It is important because for the pump to operate properly, the pressure at the pump suction must exceed the vapour pressure for the pumped fluid to remain liquid in the pump. If the vapour pressure exceeds the pressure at the pump suction, vapour bubbles will form in the liquid. This is known as cavitation and leads to a loss of pump
